Oceans aren’t at rest. Are the salt flats at rest?

the water will have a level even if the things behind it aren't

try putting a toy on a cup and then filling it with water

it's the same thing

The peak and trough between waves is irrelevant to sea level

I guess you didn't understood what I said but ok

That's why they use sea level as the starting point.. it is the baseline height of 70% of the Earth's surface

Lake Michigan is 577 feet above sea LEVEL... Lake Huron is 577 feet above sea LEVEL.. They are both equal? LEVEL? FLAT? No change. No curve. No GLOBE!!!

Something else, why do things fall common question but answer anyways

This is a smaller scale example of sea level. Lake Michigan and Lake Huron form the world's largest water level besides the oceans

Gravity is only electromagnetism

that's not how fluids work...

That is how fluids work.. that's how they built the aqueducts.. people knew this hundreds of years ago

Okay Ron im happy you didnt say density

Yes
Water is always flat
Never observed to curve

I don’t settle at EM for “gravity”.

people hundreds of years ago didn't knew how to build computers

people hundreds of years ago prayed instead of doing surgeries

Yeh nah but stil it's a better attempt than densitt and buoyancy

Moving water curves across the land. (Rivers and streams)

also water is flat? More or less

Vibration? Electric fields?

Water is affected by electromagnetism. It's otherwise perfectly flat

This is a small-scale version of the Earth

More or less, water at rest is flat. Yes.

Computers,Surgery is irrelevant
They knew how liquids work
They were not idiots

With the North Pole at the center

if you take a little piece of the ocean it's indeed flat (unless you really really zoom in)

but if you take the whole earth, then it's not flat

That water body is small and at rest.

Please show measurable curvature on water or water curving

it's just that we're too small

we need to go to space for you to see it

unfortunetly I don't have such resouces

but spaceX does

The oceans aren’t flat. They have waves.

So in other words
You can’t and only making assumptions

This is how they make glass windows with molten tin ... At 3:30 it says (("the surface of any liquid is flawlessly flat"!!!)) https://youtu.be/IjNusHQOhTM  ..  Flat liquid equals Flat Earth  .. take 10 seconds to watch that video segments

Got it 👍
